Serial network interfaces reside on modular port adapters, which provide a direct connection between the high-speed bus in the router and the external networks. The PA-E3 provides a full-duplex synchronous serial E3 interface for transmitting and receiving data at rates of up to 34 megabits per second (Mbps).

The port adapter supports both 16- and 32-bit cyclic redundancy checks (CRCs). The default is 16-bitCRCs;toenable 32-bit CRCs, you use a conﬁguration command. For a description of the CRC function, see the “Conﬁguring Cyclic Redundancy Checks” section on page 8-10.

Note Although the VIP2 and Catalyst RSM/VIP2 supports online insertion and removal (OIR),

individual port adapters do not. To replace port adapters, you must ﬁrst remove the VIP2 and Catalyst RSM/VIP2 from the chassis, and then replace port adapters as required.

The Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers support the OIR of all port adapter types.

PA-E3 Serial Port Adapter Installation and Configuration

After system initialization, the ENABLED LED goes on, indicating that the port adapter has been enabled for operation.

The following conditions must be met before the PA-E3 port adapter is enabled:

• The port adapter contains a valid microcode version that has been downloaded successfully.

• For Cisco 7000 and 7500 series routers, the port adapter is correctly connected to the VIP2 and

the midplane and is receiving power in the Cisco router.

• For the Catalyst 5000 family switches, the port adapter is correctly connected to the

Catalyst RSM/VIP2 and is receiving power in the switch.

• The bus recognizes the port adapter.

If any of these conditions are not met, or if the initialization fails for other reasons, the ENABLED LED does not go on.

PA-E3 Serial Port Adapter Installation and Configuration

Interoperability Guidelines for PA-E3 DSUs

On a single PA-E3, there are one or two serial E3 ports, each with two connectors (receive and transmit), where you connect the Cisco 75-ohm coaxial cable. The 75-ohm coaxial cable (Cisco part number CAB-ATM-DS3/E3) for the PA-E3 is available only from Cisco Systems; it is not available from outside commercial cable vendors.

The Cisco E3 75-ohm coaxial cable, which comes with an attached ferrite sleeve (see Figure 1-5), is available only in 10-foot (3.05-meter) lengths. The typical maximum distance between stations for E3 transmissions is 1300 feet (396 meters).

Note For E3 (75-ohm) connections, you must have ferrite beads on the 75-ohm coaxial cable and

EMI decoupling clips on the Rcvr end of the cable (see Figure 1-5) if compliance with European certiﬁcation standards for emission control is required (EN55022/CISPR22 Class B for radiated emission levels).

Caution

The VIP2 requires that the host Cisco 7000 series router have the RSP7000 and RSP7000CI installed. The VIP2 does not operate properly with the Route Processor (RP), Switch Processor (SP), or Silicon Switch Processor (SSP) installed in the host Cisco series router.

ThePA-E3 is considered a high-bandwidth port adapter; therefore at a minimum, Cisco recommends that the PA-E3 be installed on the VIP2-15 or Catalyst RSM/VIP2-15 motherboard (with 1 MB of SRAM and 8 MB of DRAM). Installation of the PA-E3 on the VIP2-10 (with 512 KB of SRAM and 8 MB of DRAM) is not recommended.

PA-E3 Serial Port Adapter Installation and Configuration

Safety Guidelines

Note The VIP2 and Catalyst RSM/VIP2 supports online insertion and removal (OIR), but

individual port adapters do not. To replace the port adapters, you must ﬁrst remove the VIP2 or Catalyst RSM/VIP2 from the chassis and then replace port adapters as required. OIR is supported for port adapters in the Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers. Port adaptershavea handle attached, butthis handle is occasionally not shownin illustrations in this publication to allow a full view of detail on the port adapter’s faceplate.

In the Cisco 7000 series, Cisco 7100 series, Cisco 7500 series, Cisco uBR7200 series routers and Catalyst 5000 family switches, there are no restrictions on slot locations or sequence; however, in the Cisco 7200 series routers, there are speciﬁc conﬁguration guidelines that must be observed for high-bandwidth port adapters.

For speciﬁc Cisco 7200 series hardware conﬁguration information and for memory conﬁguration guidelines for Cisco 7200 series routers, refer to the document Cisco 7200 Series Port Adapter Hardware Conﬁguration Guidelines, which shipped with your Cisco 7200 series chassis and is also available on the Cisco Connection Documentation, Enterprise Series CD-ROM.

To determine if your Cisco 7000 series, Cisco 7100 series, Cisco 7500 series, Cisco 7200 series, or Cisco uBR7200series router,or the Catalyst RSM/VIP2 is compatible with the PA-E3,use theshow version command to display the current hardware conﬁguration of the router,including the system software version that is currently loaded and running.

You can check the version of the default ROM image by removing the board and checking the ROM labels, or by conﬁguring the interface or system software to boot from ROM, restarting the system, and using the show version command to check the running version.

To display the current system software version, use the show version command. In the following example, the running system software is Release 11.1(16)CA.

Varning! Denna varningssymbol signalerar fara. Du beﬁnner dig i en situation som kan leda till

personskada. Innan du utför arbete på någon utrustning måste du vara medveten om farorna med elkretsar och känna till vanligt förfarande för att förebygga skador. Se förklaringar av de varningar som förkommer i denna publikation i dokumentet Regulatory Compliance and Safety Information (Efterrättelse av föreskrifter och säkerhetsinformation), vilket medföljer denna anordning.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis.

• Do not workalone when potentiallyhazardous conditions existand never assume that power has

been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe. Carefully examine your work area for possible hazards such as moist ﬂoors, ungrounded power extension cables, and missing safety grounds.

Electrical Equipment Guidelines

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is speciﬁcally designed for wet

locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperlyhandled,resultsincompleteorintermittentfailures.Portadaptersandprocessormodules consist of printed circuit boards that are ﬁxed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.

The following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unﬁnished chassis surface.

• When installing a component, use any available ejector levers or captive installation screws to

properly seat the bus connectors in the backplane or midplane. These devicesprevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

• When removing a component, use any available ejector levers or captive installation screws to

release the bus connectors from the backplane or midplane.

Preparing for Installation 2-5

Compliance Information

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

• Place a removed component board-side-up on an antistatic surface or in a static shielding

container. If you plan to return the component to the factory, immediately place it in a static shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects

components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should

be between 1 and 10 megohms (Mohm).

Compliance Information

The following sections provide compliance information thatapplies to the FCC andthe PA-E3 serial port adapter, which has beendesigned to meet these requirements. Modiﬁcations to this product that are not authorized by Cisco Systems, Inc., could void the various approvals and negate your authority to operate the product.

BABT Compliance

The BABT607116 marking on the PA-E3 signiﬁes that it meets United Kingdom directive 607116 and has been designed to BABT standards. The BABT label is located on the top of the PA-E3; Figure 2-1 shows the BABT label for the PA-E3.

ITI-T Compliance

ITI-T recommendation G.823 speciﬁes that it is important to restrict jitter gain. Figure 4 of G.823 shows a typical jitter transfer characteristic. (Note that small jitter gain is allowed.)British Standard 6328:Section 8.1 1990 givesthe allowablegain as 0.5 dB. The PA-E3’s line mode clocking complies with these sections.

TBR24 Compliance

WhenthePA-E3 is in line clocking mode, jitter is not attenuated, and any jitter receivedistransferred to the line. If input jitterexceedsthe limits of TBR24, then outputjitter will not meet TBR24 transfer speciﬁcations. Line clocking mode is intended for use only where the connection involves a single hop, and where clock timing will not be transferred to other network equipment.

When not in line clocking mode, the PA-E3 complies with TBR24 standards.

CHAPTER

VIP2 and the PA-E3

This chapter provides information on the PA-E3 serial port adapter and its use on the VIP2 in Cisco 7000 series and Cisco 7500 series routers. This chapter contains the following sections:

• Overview, page 3-1

• Removing a Port Adapter, page 3-4

• Installing a Port Adapter, page 3-5

Overview

The PA-E3 is used on the VIP2 in Cisco 7000 series and Cisco 7500 series routers and can be installed in either port adapter slot 0 or slot 1 on the VIP2 motherboard.

Note You can have up to three E3 serial interfaces on a VIP2 motherboard. Cisco recommends a

conﬁguration of one PA-E3 (with one E3 serial interface) and one PA-2E3 (with two serial interfaces) for a total of three E3 serial interfaces per VIP2.

Figure 3-1 shows two one-port PA-E3 port adapters installed in port adapter slot 0 and slot 1, on a VIP2-15 or VIP2-40.

Depending on the circumstances, you might need to install a new port adapter on a VIP2 motherboard or replacea failed port adapter in the ﬁeld. In either case, you need a number 1 Phillips screwdriver, an antistatic mat on which you can place the removed interface processor, and an antistatic container in which you can place a failed port adapter for shipment back to the factory.

Note The PA-E3 can be installed on a VIP2-15, VIP2-20, VIP2-40, or VIP2-50 motherboard;

however, installation on the VIP2-10 is not recommended.

Caution To prevent system problems, do not remove port adapters from the VIP2 motherboard or

attempt to install other port adapters on the VIP2 motherboard while the system is operating. To install or replace port adapters, ﬁrst remove the VIP2 from its interface processor slot.

Note Each port adapter circuit board is mounted to a metal carrier and is sensitive to ESD damage.

The following procedures should be performed by a Cisco-certiﬁed service provideronly.The VIP2 supports online insertion and removal (OIR), but individual port adapters do not. To replace port adapters, you must ﬁrst remove the VIP2 from the chassis and then install or replace port adapters as required. If a blank port adapter is installed on the VIP2 in which you want to install a new port adapter, you must ﬁrst remove the VIP2 from the chassis and then remove the blank port adapter.
